ELECTRICITY CONSUMPTION BILLING METHOD: ANALYSIS OF LARGE CUSTOMERS

Abstract

This article analyzes the billing modalities for electric energy consumption applied to large consumers in Group A, focusing on the comparison between the time-of-use blue and green tariffs. The research, applied in nature and using both quantitative and qualitative approaches, employs real consumption data from Empresa Viveiro (fictitious name) and is based on the method proposed by Cavalcante Neto (2025), which uses the peak load factor (FCponta) as the main decision parameter. Through documentary research, case study, and tariff simulation, the study aims to identify the most efficient tariff modality from technical, economic, and operational perspectives. The results revealed inconsistencies in the tariff classification of three out of the five analyzed Consumer Units, indicating significant potential for cost reduction through contractual review. It was found that FCponta values above 0.70 favor the blue tariff, while lower values make the green tariff more advantageous, consistent with theoretical models. The study concludes that periodic tariff reassessment, along with active management of consumption patterns, is essential for cost optimization and operational efficiency. It reinforces the importance of analytical tools in decision-making and demonstrates that contractual adjustments, even without additional infrastructure investments, can lead to substantial reductions in the final electricity cost for large consumers.
